Development Workflow

Get the code

  $ git clone https://github.com/openshift/openshift-sdn.git
  $ git clone https://github.com/openshift/cluster-network-operator.git

Do your changes

Create the image

  $ make build-image-sdn-test

This will call podman under the hood and it'll create an image with your changes for openshift/sdn

Push your image to quay.io

  $ podman push sdn-test quay.io/<your_quay_user>/sdn-test:latest

Deploy a cluster with your changes

Using Cluster Network Operator

  1. Create a directory for your deployment
    $ mkdir /tmp/deployment

  1. Get your openshift-install binary and your pull-secrets

  2. Go to your Cluster Network Operator (CNO) Directory

  3. Run hack/run-locally

    $ hack/run-locally.sh -i <your_openshift_install_path> \
          -c <your_install_directory> -n <sdn|ovn> \
	  -m <your_quay_image_path>

Using Cluster-Bot

This assumes you already have a PR around, and access to cluster-bot under the CoreOS Slack channel.

Just query cluster-bot and send him a message with the following:

  launch openshift/sdn#<PR_NUMBER> aws

Update your CNO image without deleting your cluster

  update_cno ()
  {
      oc patch clusterversion version --type json -p '[{"op":"add","path":"/spec/overrides","value":[{"kind":"Deployment","group":"apps","name":"network-operator","namespace":"openshift-network-operator","unmanaged":true}]}]'
  }

  custom_sdn ()
  {
      update_cno;
      oc -n openshift-network-operator delete deployment network-operator;
      oc -n openshift-sdn set image ds/sdn sdn=quay.io/<your_quay_user>/sdn-test
  }

Destroying your cluster once you're done

Using Openshift Installer

  $ openshift-install destroy cluster --dir <your_install_directory>

Using Cluster-Bot

  done
